Hi Folks,
At this link you can see how a traditional navaja is made. Ufortunately the text is in Spanish, but the pictures pretty much say it all. Note how all the tools are quite archaic. It is because such labour intensive methods are used, that a traditional navaja costs so much and why by the end of the 19th century the Spanish cutlery industry was completely uncompetitive against its European counterparts
